Bots and Automation over Twitter during the U.S. Election

“We find that that political bot activity reached an all-time high for the 2016 campaign. (1) Not only did the pace of highly automated pro-Trump activity increase over time, but the gap between highly automated pro-Trump and pro-Clinton activity widened from 4:1 during the first debate to 5:1 by election day. (2) The use of automated accounts was deliberate and strategic throughout the election, most clearly with pro-Trump campaigners and programmers who carefully adjusted the timing of content production during the debates, strategically colonized pro-Clinton hashtags, and then disabled activities after Election Day.”
